Michelle O'Brien, a 30-year-old Austin resident, was infected with Vibrio Vulnificus -- a flesh-eating bacteria found in warm bodies of salt water or contaminated raw seafood -- after cutting her foot on an oyster bed Saturday on Galveston Island, ABC13.com reports.

The bacterium can cause fever and chills, decreased blood pressure, skin lesions and death, according to the Centers for Disease Control and Prevention. The CDC says 50 percent of infections are fatal.
